It operates from a wide range of power ranging from +5 Volts to +18 Volts supply voltage. Sinking or sourcing 200 mA of load current. The external components should be selected properly so that the timing intervals can be made into several minutes along with the frequencies exceeding several hundred kilohertz. The output of a 555 timer can drive a transistor-transistor logic (TTL) due to its high current output. It has a temperature stability of 50 parts per million (ppm) per degree Celsius change in temperature which is equivalent to 0.005 %/ °C. The duty cycle of the timer is adjustable. Also, the maximum power dissipation per package is 600 mW and its trigger and reset inputs has logic compatibility.
